Description
Serial Peripheral data transfer flag
Cleared by hardware to indicate data transfer is in progress or has been approved by a
clearing sequence.
Set by hardware to indicate that the data transfer has been completed.
Write Collision flag
Cleared by hardware to indicate that no collision has occurred or has been approved by a
clearing sequence.
Set by hardware to indicate that a collision has been detected.
Synchronous Serial Slave Error flag
Set by hardware when SS is de-
asserted before the end of a received data.
Cleared by disabling the SPI (clearing SPEN bit in SPCON).
Description
Clock Phase
Cleared to have the data sampled when the SCK leaves the idle state (see CPOL).
Set to have the data sampled when the SCK returns to idle state (see CPOL).
